So Ive seen many threads with the similar problem but I did not find a solution.
- I go to Connect/share -> start server and I server started at IP 10.250.xx.xxx:8080
- I go to that address in my brower on my PC (windows 10 64bit) and the library works
- then I go to the address on my samsung galaxy s9, connected to the same wifi of my PC, but says "Hmm... can't reach this page ERR_ADDRESS_UNREACHABLE"
- On PC, wifi network is set to private, PC is discoverable, and calibre.exe and calibre-server.exe added to firewall exception
- I also tried to pause antivirus and pause firewall completely
- I have not a VPN running
